Superior Battery Technology - Uses rechargeable Lithium-ion polymer (LiPo) batteries, which are used in laptops, IPhone, IPad, and even electric vehicles. Rechargeable lithium-based technology currently provides the best performance for your solar light bulb. In energy terms, Li-ion batteries simply pack a more powerful punch. Li-ion batteries store more energy in smaller spaces than the more traditional lead-acid and nickel-metal-hydride ones. Lithium has the most energy density and electrochemical potential of all metals, which is what gives it that stamina.
